SPEGIFIGATION forming part of Letters Patent No. 720,831, dated February17, 1903.

Application filed June 26, 1902. fierial No. 113,258. (No model.)

To all whom, it may concern:

Be it known that I, J ens NILSSON MAUN- TIN, manufacturer, a subject ofthe King of Sweden and Norway,and a resident of Kampegata'n, Goteborg,in the Kingdom of Sweden, have invented certain new and usefulImprovements in Roof-Tiles, of which the following is a specification,reference being made to the accompanying drawings.

This invention relates to such roof-tiles as are on their upper sideprovided with longitudinal channels or flutes for facilitating therunning off of the rain-water and at which adjacent tiles are connectedto one another by means of chute-shaped pieces, which consist ofmetalforinstance, zinc-or other suitable material and which clasp, ribswhich are formed by grooves in the adjacent lateral portions of thetiles.

, Roof-tiles arranged according to this invention differ from olderroof-tiles of the kind in question, partly therein that they are ontheir lower side provided with ridges or the like extending from thelower edge of the tile t0 the upper edge of the same and having such ashape as to correspond to the channels or flutes on the upper side ofthe tiles and partly therein that the grooves extending along thelateral edges of; the tiles and into which engage the chute-shapedpieces, serving to connect adjacent tiles and at some distance from thelower edge of the tiles, in con-.

sequence of which the chutes can be open at both ends and need not beclosed at their upper end.

Figure 1 shows a cross-section of a roof-tile carried out according tothis invention and of parts of the adjacent tiles. Fig. 2 shows thelower side of such a roof-tile, while Figs. 3 and 4 show a plan View anda cross-section, respectively, of a metal chute. Fig. 5 shows some tilesarranged according to this invention and placed close to one another,the fixing-lugs of the tiles being turned alternately upward anddownward.

The roof-tile 1 is, as mentioned above, provided with the ordinarychannels or flutes 2 for facilitating the running off of the rain-water.

On the lower side of the tile there are ridges edge of the tile to theupper edge of the same or to the fixing-lug 4, situated at thelastmentioned edge, the shape of these ridges corresponding to the shapeof the channels or flutes on the upper side of the tile. By thearrangement on the lower side of the tile of ridges extending from thelower edge to the upper edge or to the fixing-lug, in consequence ofwhich arrangement the shape of the under side of the tile will fullycorrespond to the shape of the upper side, is gained the advantage thatthe .tiles of two successive layers, one above the other, fit snugly toone another, not only when entire tiles are used, but also when thetiles are cut off, either obliquely, as at the intersection of twooblique roof-surfaces, or transversely, as at a chimney-shaft. Thejoints between'the tiles of two successive layers will therefore becomecompletely tight. Another advantage with the arrangement in question isthat breakage of the tiles at their transport is considerably reduced,as the tiles can be placed close to one another, as clearly shown inFig. 5.

The roof-tiles in question are also characterized thereby that thegrooves 5, situated at the lateral edges of the tile and into whichengage chutes 6, serving to hold adjacent tiles togethelgdo not, ashitherto, extend to the lower edge of the tiles, but end at somedistance from the same, each groove being thus limited at its lower endbyawall 7, Fig. 2. As these walls 7 prevent a sliding downward of thechutes 6 engaginginto the grooves 5, the chutes need not be providedwith a transverse wall at their one end, but they may instead be open atboth ends. By this is attained not only that the manufacture of thechutes will be easier and cheaper, but also that when pushing a chute ona rib 8, formed by the lateral portions of two adjacent tiles, thebroader end of the chute may form the forward end, (the one end of thechute is usually somewhat broader than the other,) whereby of course thepushing of the chute on the rib is facilitated. Another advantage withchutes open at both ends is that the chutes may be pulled downward orupward from without-when the roof is repaired or altered.

Having now described my invention, what I claim as new, and desire tosecure by Letters In witness whereof I have hereunto set my Patent, ishand in presence of two witnesses.

A roof-tile having grooves along its edges s NILSSON MAUNTIN extendingfrom its upper edge to a point short 5 of its lower edge to leave anintact portion to fitness?! act as a stop for the connecting-chute, sub-TH. AKERMARK, st-antially as described. V. WESTNESS.
